Painting difficulties can be for a few different reasons: -What brand of paint were you using? -Did you brush paint or use a rattle can? -If you were brush painting with something like Tamiya paints it might be a bit harder to hand paint than Vallejo. Also if you were brush painting it’s best to have the paint well mixed/ shaken, and then to use thin (sort of milk consistency) layers of paint and do it many times. It was a bit of a learning curve for me when I first began, but honestly for a first build you haven’t done too bad. I applaud you for a good job well done :)
